There’s a method to send Bitcoin from Earth directly to Mars within three minutes, using technology that is already available. Just need to find someone who will accept it.
Last month, Jose E. Puente published an article with his friend, Carlos Puente. white paper unveiling Proof-of-Transit Timestamping — a concept he told Cointelegraph is the missing piece needed to make Bitcoin interplanetary.
According to the concept, if in the near future an individual Bitcoin user wishes to send money to Mars, the payment could be sent via different stations. These include ground antennas and satellites.
The transaction takes place at each of the stops “stamped” Before continuing to its final destination.
Puente told Cointelegraph that PoTT is the official acronym for PoT. “receipt layer” Bitcoin and Lightning Network, while using optical links created by Elon Musk’s Starlink or the National Aeronautics and Space Administration.
“The technology is essentially ready. The moment there’s a stable Earth–Mars link, PoTT can ride on top, making Bitcoin the first currency to operate cleanly across planets,” “He said”
“By simulating Mars-level delays, we could run a convincing end-to-end demo right now.”
Puente stated that Bitcoin Lightning transfers can reach Mars within three minutes or 22 minutes if the worst case scenario occurs.
Puente suggested a possible solution to the blackout on Mars every 26 months. “deliberately route around the Sun with relay satellites” Avoid the blackout.
Puente explains that PoTT works like the normal Bitcoin timestamping, except it is extended to the outer space.
“Imagine it’s 2050 and you’re sending money from Earth to your friend on Mars to help pay for their rent. Because the planets are so far apart, the message has to hop through different stations.”
“At each stop, that station stamps the message with the time it arrived and the time it left, like a passport getting stamped at every border crossing. By the time the message gets to Mars, you can look at all the stamps and see the exact path it took and when it moved.”
Puente says PoTT may be put to the test today.
Bitcoin has made its way to outer space
Blockstream created the original concept back in December 2018. connected Bitcoin to five satellites Space Bitcoin transactions are now possible. Spacechain then completed its claim that it would be the first Bitcoin transaction in outer space by August 2020. first Bitcoin transaction Bitcoin is a cryptocurrency that can be seen in space (International Space Station)BTCYou can receive a Message from Earth.

Of course, for a Bitcoin transaction to occur on Mars, a human — or an AI — would need to be there, and that hasn’t happened yet. NASA, other space agencies and only landers orbiters and robots have so far explored Mars.
It would be necessary to have someone willing to accept Bitcoin. Blue Origin is a Jeff Bezos company. started accepting crypto — including Bitcoin, Ether (ETH), Solana (SOL), and stablecoins Tether (USDTUSDCUSDC) — last month, but so far they’ve only made it past the Kármán line, about 100 kilometers from Earth.
Musk is also in agreement that standard money will be needed.
Musk’s SpaceX wants to get there Mars by the end of 2026 With a long term ambition of building a self-sustaining town there.
Musk also agrees, along with Puente that there is a need to have a standard currency for transactions between Earth and Mars. He had previously expressed concern Puente explained that Lightning Network is a solution to the 10-minute Bitcoin block time.
“PoTT plus Lightning provide the practicality Musk asked for: local speed with global settlement that works across planets.”
He initially dismissed Bitcoin in January last year, but eventually accepted that Lightning Network could make interplanetary payments more possible.

“If we’re serious about a multi-planet civilization, we need an open, neutral monetary base that doesn’t depend on any single company, government, or ground station,” Puente argued that Bitcoin was the best interplanetary currency.
“That’s why we focused on Bitcoin as the shared standard and designed PoTT as a practical way to move value across vast distances while preserving accountability and individual agency.”
PoTT can be used on any planet
Puente stated that PoTT has been built as a system to work across any habitable zone of a star. “travel receipts” It generates can be reached by transactions sent to any planet or the Moon.
He said the research just focused on Earth and Mars as it is the “cleanest near-time case study.”
